This application claims the benefit of US Provisional Application No. 60 / 801,182, filed May 17, 2006.

Higher temperature solution processes for olefin polymerization are highly desirable due to increased throughput, reduced energy required for devolatilization and reduced deposits due to these higher temperatures. Although Ziegler-Natta catalyst systems can be carried out commercially at high temperatures, these catalysts suffer from poor efficiency and poor comonomer introduction at elevated temperatures. In addition, polymers prepared at elevated temperatures from Ziegler-Natta catalysts have an extended molecular weight distribution, which limits their suitability for use in many applications. Conventional Ziegler-Natta catalysts typically consist of a plurality of types of catalyst species, each of which has a different metal oxidation state and a different coordination environment with the ligand. Examples of such heterogeneous systems are known and include metal halides activated with organometallic cocatalysts, such as titanium chloride supported on magnesium chloride, activated with organoaluminum and organoaluminum halide cocatalysts. Because these systems contain more than one catalytic species, they have a variety of capacities for introducing comonomers in polymer chains and polymer chains with different activities. The result of this multi-site chemistry is a product with poor control of the polymer chain structure. In addition, differences in individual catalyst sites produce polymers having high molecular weight at some sites and low molecular weight at other sites, resulting in polymers having a broad molecular weight distribution and non-uniform composition. Due to the heterogeneity, the mechanical and other properties of the polymer may be inferior to what is desired.

More recently, catalyst compositions based on well-defined metal complexes, especially transition metal complexes such as constrained geometry catalysts (CGCs), metallocenes and post-metallocenes, have shown high comonomer introduction rates and narrow molecular weight distributions. It was shown to provide a product having. However, these catalysts often have poor high temperature stability and also suffer poor efficiency at elevated polymerization temperatures. In addition, the molecular weight of polymers formed from these catalysts often decreases dramatically with increasing temperature, especially for polymers containing significant amounts of comonomers (low density). That is, the ability of most olefin polymerization catalysts to introduce higher α-olefins into the ethylene / α-olefin copolymer more highly depends on the increase in polymerization temperature due to the fact that the reactivity ratio, r ₁ , depends on the polymerization temperature. Decreases.

Reactivity ratios of catalysts are described, for example, in "Linear Method for Determining Monomer Reactivity Ratios in Copolymerization", M. Fineman and SD Ross, J. Polymer Science, 5, 259 (1950) or in "Copolymerization", FR Mayo and C. Walling, Chem. Rev., 46, 191 (1950)]. One widely used copolymerization model is based on the following scheme.

Wherein, M _i represents the named monomer molecule optionally as "i", and where _{i = 1, 2, M 2} * represents a polymer chain growing the i monomers are coupled to the last.

The k _ij value is the rate constant for the reaction described. For example, in ethylene / propylene copolymerization, k ₁₁ represents the rate at which ethylene units are inserted into the growing polymer chain, where the previously inserted monomeric units are also ethylene. Reactivity ratios follow "r ₁ = k ₁₁ / k ₁₂ " and "r ₂ = k ₂₂ / k ₂₁ ", where k ₁₁ , k ₁₂ , k ₂₂ and k ₂₁ indicate that the last polymerized monomer is ethylene Rate constant for the addition of ethylene (1) or propylene (2) to a catalyst site that is (k _1x ) or propylene (k _2x ).

Specific posts based on Group 4 metal complexes of bridged divalent aromatic ligands containing group 3 to 6 or lanthanide metal complexes, preferably divalent Lewis base chelating groups, for use in olefin polymerization Metallocene catalyst compositions are disclosed in USP 6,827,976 and US 2004/0010103. In general, these metal complexes are commonly used for solution polymerization at elevated temperatures. However, their use at higher reaction temperatures in the preparation of ethylene / α-olefin copolymers often results in polymers having high I ₁₀ / I ₂ , which is high in the in-situ of the long chain monomers formed in situ under the polymerization conditions used. It is believed to be due to the level of entry (long chain branching). In many applications, the presence of such long chain branching can provide polymer products with advantageous properties due to increased processability and green-strength while maintaining a narrow molecular weight distribution. However, for certain other applications, such as films, fibers and adhesives, high levels of long chain branching may be undesirable. In particular, the poorer tearing properties, poorer fiber formation and stretching properties, and reduced hot tack strength of films made from such polymers can be correlated to increased I ₁₀ / I ₂ values. Thus, there is provided a post metallocene catalyst having the ability to prepare interpolymers of ethylene with one or more C _3-20 α-olefins with lower I ₁₀ / I ₂ values while maintaining good high temperature operating conditions. It is desirable to.

In addition, the solubility of aliphatic or cyclic aliphatic hydrocarbon solvents of this class of post metallocene metal complexes is often lower than desired. Catalyst solubility is very important from an industrial point of view to maximize catalyst efficiency and reduce catalyst transport volume. The greater the amount of metal complex that can be dissolved in a given volume of solvent, the greater the reduction in storage and transportation costs. In addition, catalyst poisoning due to the spontaneous generation of impurities in the solvent becomes a significantly greater problem as concentrations are limited. Many of the catalysts are sacrificed or lost due to poisoning.

Therefore, it is highly desirable to select catalyst compositions that can form ethylene / a-olefin copolymers with increased efficiency at elevated reaction temperatures and form polymers having reduced or low I ₁₀ / I ₂ . The use of catalysts with increased solubility in aliphatic or cyclic aliphatic hydrocarbons is also highly desired.

US 2005/0215737 A1 discloses a process for the continuous solution polymerization of olefins for producing ethylene-butene and ethylene-propylene interpolymers at high ethylene conversion.

Particularly for the industrial production of high molecular weight polyolefins in a continuous solution process, under the conditions of a relatively high reactor temperature, the polymerization reaction is carried out at a high conversion rate of the olefin monomer to the polymer in a reactor having a high solids content, all at a high catalytic efficiency. Is particularly preferred. The combination of these process requirements severely limits the choice of metal complexes that can be suitably used. Metal complexes suitable for use under lesser requirements may in fact not be acceptable for use under commercial process conditions. Particularly desirable are metal complexes which are relatively good comonomer introducers over a wide temperature range with limited ability to introduce longer chain comonomers.

WO 99/45041 discloses another process for the continuous solution polymerization of olefins using noncoordinated anionic cocatalysts and bridged hafnocene complexes. The resulting polymers contained significant amounts of comonomers, but the catalyst efficiency was relatively low and the polymer molecular weight was lower than desired even in the absence of a chain transfer agent.

WO 03/102042 discloses a high temperature solution polymerization process of olefins for producing polyolefins at temperatures in excess of about 130 ° C. using indenoindolyl transition metal complexes. In one example, copolymerization of ethylene and 1-hexene was performed at 180 ° C. resulting in the formation of a polymer with poor comonomer incorporation (density = 0.937 g / cm ³ ) with relatively low catalyst efficiency.

We believe that in the present invention, certain metal complexes contain relatively large amounts of introduced C _3-8 α-olefin comonomers while maintaining relatively low I ₁₀ / I ₂ values (which are indicative of reduced long chain branching formation). It has been found that it can be used in a solution polymerization process to produce relatively high molecular weight ethylene containing interpolymers. In addition, the solubility (measured as solubility at 20 ° C. in methylcyclohexane, hexane or mixed hexanes) in aliphatic or cyclic aliphatic hydrocarbons of these metal complexes was found to be very unpredictably high. Thus, the present invention provides a process for producing such olefin polymer products, in particular high molecular weight polyethylene interpolymers having reduced I ₁₀ / I ₂ values with very high catalytic efficiency.

Embodiments of the present invention provide a novel solution process for preparing olefin polymers using catalyst compositions comprising transition metal complexes at high catalyst efficiency at high temperatures, wherein the resulting polymers are introduced at varying densities ( And the relatively low I ₁₀ / I ₂ values. Of particular importance is the ability to produce high molecular weight ethylene / α-olefin interpolymers at reaction temperatures of 130 to 200 ° C. under high conversion conditions with very high catalytic efficiency. These polymers preferably have a narrow molecular weight distribution (M _w / M _n ) of at most 3.0, preferably at most 2.7, most preferably at most 2.4, 0.850 to 0.950, more preferably 0.860 to 0.930, most preferably 0.865 Comonomer content giving a polymer density of from 0.9 to 0.920, and I ₁₀ / I ₂ of 10 or less, more preferably 6.0 to 10.0. Such polymers are suitably used when improved extrusion performance is desired, such as in polymers of molding and extrusion grades, especially in films, fibers or wire and cable insulation articles.

The term "polymer," as used herein, refers to a polymeric compound prepared by polymerizing one or more monomers. Polymers refer to homopolymers, copolymers, terpolymers, interpolymers, and the like. The term “interpolymer” herein refers to a polymer comprising two or more copolymerizable monomers in polymerized form or introducing long chain branches as a result of chain termination / olefin formation reactions in situ and reintroducing olefins formed in situ. It is used interchangeably with the term copolymer for this purpose. Thus, copolymers can be produced from the polymerization of single monomers under precise operating conditions. The smallest proportion of monomer in the resulting copolymer or interpolymer is generally referred to by the term "comonomer". The chain length of the abovementioned long chain branch is consequently longer than the carbon length resulting from the polymerization of any finely added comonomer, in particular more than 6 carbon atoms. The presence of long chain branches can be detected by the increased shear sensitivity of the polymer, as disclosed in EP-A-608,369 and the like. Preferably for use herein, there are very few long chain branches. Preferred polymers according to the invention have a melt index ratio (MIR), in particular I ₂₁ / I ₂ of less than 30 or an I ₁₀ / I ₂ value of less than 10, which is the ratio of polymer melt viscosity measured under different loads. In addition, a method and a polymer produced therefrom is from 0.01 to 50, preferably 0.1 to 30, most preferably MI is equation for polymer melt index (MI) of 0.3 to 10 range: "I ₁₀ / I ₂ ≤ 10.32 (MI) ^-0.0814 ".

Preferred interpolymers are ethylene / 1-octene copolymers containing 2 to 20, preferably 3 to 12 mole percent octene comonomers.

Polymerization conditions generally refer to temperature, pressure, monomer content (including comonomer concentration), catalyst concentration, cocatalyst concentration, monomer conversion, or other conditions that affect the properties of the resulting polymer. By working in accordance with the desired polymerization conditions of the present invention, high molecular weight polymers can be prepared having high catalytic activity, low cocatalyst utilization and a relatively high comonomer introduction rate with high I ₁₀ / I ₂ or MIR. In particular, activities exceeding 0.5 g / μg, preferably greater than 0.55 g / μg and even greater than 0.6 g / μg (based on the weight of the polymer relative to the weight of the transition metal) are possible. The solubility of the metal complex is preferably a hydrogenated propylene dimer commercially available as hexane, methylcyclohexane or mixed hexane (Isopar E ^™ available from ExxonMobil Chemicals Inc.). ) Is at least 5% by weight and preferably at least 6% by weight at 20 ° C.

Polymer weight-average molecular weight (M _w ) is determined by gel permeation chromatography, one of which techniques is described in USP 5,272,236. Alternatively, melt indexes I ₂ , I ₁₀ or I ₂₁ , measured according to ASTM D-1238, for example, can be used as an indicator of molecular weight. In general, the melt index is inversely proportional to the molecular weight of the polymer. The higher the molecular weight, the lower the melt index, but the relationship is not necessarily linear.

One embodiment of the invention involves a process comprising contacting ethylene with at least one C _3-8 α-olefin, and optionally conjugated diene, in a continuous solution polymerization process. The process of the invention provides a reaction mixture (or individual component thereof), optionally comprising a metal complex, a cocatalyst, ethylene and at least one C _3-8 α-olefin comonomer, and any diolefin. It is particularly advantageous for use under polymerization conditions in which, in the presence of chain transfer agents, are continuously or intermittently added to a reactor operated under solution polymerization conditions and the polymerization product is removed therefrom continuously or semi-continuously. The process is preferably carried out with zirconium complexes and approximate chemical formulas under continuous solution polymerization conditions at temperatures of 100 to 200 ° C., preferably 120 to 190 ° C., under high ethylene conversion conditions (> 85%, preferably> 90%). _{(C 14-18 H 27-35) 2 CH} 3 N] + [B (C 6 F 5) 4] - in the co-catalyst, and optionally an alumoxane scan using the scavenger at least one kinds of ethylene and C _{3- 8} α-olefins and / or diolefins are polymerized to give a density of 0.850 to 0.950 g / cm ³ , preferably 0.860 to 0.930 g / cm ³ , most preferably 0.865 to 0.920 g / cm ³ , 0.01 to 50.0, Polymers having a melt index (I ₂ ), narrow molecular weight distribution (M _w / M _n <3.0, preferably <2.7, in particular <2.5), preferably from 0.1 to 30.0, most preferably from 0.3 to 10.0, g _polymer / μg catalyst efficiency and 0.0 to 2.5 mol% of _metal in excess, preferably 0.01 to 2.0 mole% of chain transfer by the concentration It involves the castle.

When using a chain transfer agent, an amount sufficient to cause a significant decrease in molecular weight (> 10%) as compared to comparative polymerization without a chain transfer agent is used. Very preferably, the amount of chain transfer agent used is adjusted to produce a polymer with 50,000 or more M _n . Most preferred chain transfer agent is hydrogen.

Surprisingly, the metal complexes of the present invention can form very high molecular weight polymers under a variety of polymerization conditions while maintaining a narrow molecular weight distribution (<3.0) and catalytic efficiency of greater than 0.5 g _polymer / μg _metal , thus using chain transfer agents. To adjust the molecular weight. In particular, it is surprising that the density (comonomer content) is relatively unaffected by the polymerization temperature and the long chain branching is minimized compared to other catalysts of the existing type with different substituents. This allows for the efficient production of ethylene / a-olefin interpolymers having relatively low I ₁₀ / I ₂ with varying levels of comonomers.

Such metal complexes can be conveniently prepared by standard metallization and ligand exchange procedures that include a source of transition metals and a neutral polyfunctional ligand source. The technology used is the same or similar to those disclosed in USP 6,827,976 and US 2004/0010103 and the like.

The metal complex is activated and combined with the cocatalyst to form the active catalyst composition. Activation can occur prior to adding the catalyst composition to the reactor in the presence or absence of other components of the reaction mixture, or can occur in situ by separately adding the metal complex and the activating cocatalyst to the reactor.

Activation takes place in a variety of ways to provide a catalytic compound having an empty coordination site for coordinating, intercalating and polymerizing addition polymerizable monomers, in particular olefin (s). For the purposes of this specification and the appended claims, the term “activator” or “cocatalyst” is defined as any compound, component or method capable of activating a metal complex in this manner. Non-limiting examples of suitable activators include Lewis acids, noncoordinating ionic activators, ionization activators, organometallic compounds, and combinations of these materials capable of converting neutral metal complexes into catalytically active species. As used herein, the term "non-coordinating" is not coordinating to the catalyst precursor and the active catalytic species derived therefrom or is only unstable to be substituted by neutral Lewis bases such as olefins by weakly coordinating to such complexes or species ( labile) means a substance (solvent, anion, cocatalyst or cocatalyst residue).

While not wishing to be limited by these considerations, in one embodiment of the invention, catalytic activation may include the formation of cationic, partially cationic or amphoteric species by proton transfer, oxidation or other suitable activation process. It is considered to be. The present invention is independent of whether such identifiable cationic, partially cationic or amphoteric species are actually formed during the activation process (also referred to herein interchangeably as "ionization" process or "ion activation process"). It should be understood that it is feasible and fully possible.

The ionization cocatalyst may contain an active proton, or some other cation associated with, but only weakly coordinated with, the anion of the ionizing compound. Such compounds are disclosed in EP-A-570982, EP-A-520732, EP-A-495375, EP-A-500944, EP-A-277003 And EP-A-277004 and US Pat. Nos. 5,153,157, 5,198,401, 5,066,741, 5,206,197, 5,241,025, 5,384,299 and 5,502,124. Ammonium cation containing salts in the activator, in particular _{trihydrocarbyl} -substituted ammonium cations containing one or two C _10-40 alkyl groups, in particular methylbis (octadecyl) -ammonium- and methylbis (tetradecyl) Preference is given to ammonium cations and uncoordinated anions, in particular tetrakis (perfluoro) arylborate anions, especially those containing tetrakis (pentafluorophenyl) borate. It is also understood that the cation may comprise a mixture of hydrocarbyl groups of different lengths. For example, there are protonated ammonium cations derived from commercially available long chain amines comprising a mixture of two C ₁₄ , C ₁₆ or C ₁₈ alkyl groups and one methyl group. Such amines are available under the tradename Kemamine ^™ T9701 from Chemtura Corp. and also under the tradename Armeen ^™ M2HT from Akzo-Nobel. Most preferred ammonium salt activator is methyldi (C _14-20 alkyl) ammonium tetrakis (pentafluorophenyl) borate.

Activation methods using ionizing ionic compounds that do not contain active protons but are capable of forming active catalyst compositions, such as the above-described coordinating salts of non-coordinating anions, are also contemplated for use herein, which is EP-A-426637. , EP-A-573403 and US Pat. No. 5,387,568. Strong Lewis acids, in particular tris (perfluoro) aryl borane compounds, such as tris (pentafluoro), which can form uncoordinated counter anions for cationic derivatives of metal complexes by removal of ligand groups, especially hydrocarbyl ligands The use of phenyl) borane is also included.

No. 6,395,671, may be suitably used to activate the metal complexes of the present invention for olefin polymerization. Can be. In general, these cocatalysts are exemplified by those having imidazolides, substituted imidazolides, imidazolinides, substituted imidazolines, benzimidazolides or substituted benzimidazolides anions Can be expressed as follows.

Combinations of activators, for example Combined alumoxanes and ionization activators are also contemplated in the present invention (eg, EP-A-0 573120, PCT Patent Application Publication Nos. WO 94/07928 and WO 95/14044 and US Pat. No. 5,153,157). And US Pat. No. 5,453,410.

Another suitable class of organometallic activator or cocatalyst is alumoxane (also referred to as alkylaluminoxane). Alumoxanes are activators known to be used with metallocene type catalyst compounds for the preparation of addition polymerization catalysts. There are various methods of making alumoxanes and modified alumoxanes, non-limiting examples of which are described in US Pat. Nos. 4,665,208, 4,952,540, 5,091,352, 5,206,199, 5,204,419, 4,874,734, 4,924,018, 4,908,463, 4,968,827, 5,308,815, 5,329,032, 5,248,801, 5,235,081, 5,157,137, 5,103,031, 5,391,793, 5,391,529, 5,693,838, 5,731,253, 5,731,451, 5,744,656; European Patent Application Publications EP-A-561476, EP-A-279586 and EP-A-594218; And PCT Patent Application Publication No. WO 94/10180. Preferred alumoxanes are Lewis acid modified alumoxanes, in particular tri (C _3-6 ) alkylaluminum modified methylalumoxanes such as tri (isobutyl) aluminum modified metallumoxanes (Azozo Nobel, Incorporated (Akzo Nobel) Commercially available as MMAO-3A from Co., Inc.) or tri (n-octyl) aluminum modified metallumoxane (Azo Nobel, commercially available as MMAO-12 from Incorporated).

It is within the scope of the present invention to use alumoxane (s) or modified alumoxane (s) as activator or as tertiary component in the process of the present invention. That is, the compounds may be used alone or in neutral or ionic, such as tri (alkyl) ammonium tetrakis (pentafluorophenyl) borate compounds, trisperfluoroaryl compounds, polyhalogenated heteroborane anions (WO 98/43983). As disclosed), and combinations thereof. When used as tertiary components, the amount of alumoxane used is generally less than that required to effectively activate the metal complex when used alone. Although not wishing to be limited by this consideration, in the present embodiment, it is believed that alumoxane does not significantly contribute to the actual catalyst activation. Nevertheless, it should be understood that some involvement of alumoxane in the activation process is not necessarily excluded.

Suitable alumoxanes are polymer or oligomeric alumoxanes, in particular methylalumoxane (MAO) as well as Lewis acid modified alumoxanes, in particular trihydrocarbs having from 1 to 10 carbons in each hydrocarbyl or halogenated hydrocarbyl group Billuminum-, halogenated tri (hydrocarbyl) aluminum- or halogenated tri (hydrocarbyl) boron modified alumoxanes. Such activation cocatalysts have been previously disclosed in USP 6,214,760, 6,160,146, 6,140,521 and 6,696,379 and the like. Preferred Lewis acid modified alumoxane compounds each have an i-butyl content of 10-30, preferably 15-25 mol% and an n-octyl content of 10-20, preferably 12-18 mol% Mole% is based on total alkyl ligand content) tri (i-butyl) aluminum modified metallumoxane and tri (n-octyl) aluminum modified metallumoxane. The alumoxane or Lewis acid modified alumoxane activator is preferably used in a molar ratio of cocatalyst: catalyst of 20 to 200, more preferably 20 to 150, most preferably 20 to 80.

The zirconium complexes of the present invention, due to their ability to be activated with relatively low levels of alumoxane or Lewis acid modified alumoxane cocatalysts while maintaining high catalytic efficiency, are cocatalysts in the resulting polymers with the formation of long chain branches in the resulting polymers. Reduction of by-product levels can be achieved. Such polymers are particularly suitable for use in application needs, such as where high clarity or low dielectric constant is required.

Monomer

Suitable olefin mixtures for use herein include mixtures of ethylene and one or more C _3-8 α-olefin comonomers, and optionally one or more conjugated or nonconjugated dienes. Preferred comonomers are propylene, isobutylene, 1-butene, 1-pentene, 1-hexene, 4-methyl-1-pentene, 3-methyl-1-butene, 3-methyl-1-pentene, 4- Methyl-1-pentene and 1-octene include, but are not limited to.

Suitable conjugated or nonconjugated dienes include straight chain, branched chain or cyclic hydrocarbon dienes having 4 to 15 carbon atoms. Examples include 1,3-butadiene, 1,3-pentadiene, 1,3-hexadiene, 1,4-hexadiene, dicyclopentadiene, norbornadiene, ethylidenenorbornene and mixtures thereof This includes, but is not limited to. Most preferred diene is 5-ethylidene-2-norbornene (ENB).

In general, the polymerization can be achieved at conditions known in the art for olefin solution polymerization. Preferred polymerization temperatures depend on the comonomer content of the resulting polymer. For polymers having a density in the range of 0.855 to 0.885 g / cc, the preferred temperature range is 120 to 250 ° C, more preferably 150 to 220 ° C. For polymers having a density in the range of 0.885 to 0.955 g / cc, the preferred temperature range is 150 to 250 ° C, more preferably 180 to 250 ° C. Preferred polymerization pressures are from atmospheric pressure to 3000 atmospheres (100 kPa to 300 MPa), more preferably 1 MPa to 10 MPa. Used in the majority of the polymerization catalyst the molar ratio of polymerizable compound is 10 ^-12: 1 to 10 ^-1: 1, more preferably from 10 ^-11: 1: 1 to 10 ^-5. Very preferably, the reaction is successively added to a reactor operating under continuous solution polymerization conditions, ie the monomer (s) are operated under solution polymerization conditions and the polymerized product is recovered by continuous or semi-continuous removal or recovered in a second reactor. Is carried out under conditions of sending.

Preferably, the polymerization mixture comprises an aliphatic or cycloaliphatic liquid diluent. Examples of such aliphatic or cycloaliphatic liquid diluents include straight and branched chain hydrocarbons such as isobutane, butane, pentane, hexane, heptane, octane and mixtures thereof; Alicyclic hydrocarbons such as cyclohexane, cycloheptane, methylcyclohexane, methylcycloheptane and mixtures thereof; And is the buffer containing the fluorinated hydrocarbons such as perfluorinated C _{4 -10} alkanes and the like.

Hydrogenated oligomeric aliphatic hydrocarbon mixtures sold under the tradename Isopar ™ E.

Preference is given to using molecular weight regulators or chain transfer agents in the process of the invention. Examples of such molecular weight modifiers include hydrogen, trialkyl aluminum compounds, or other known chain transfer agents. Hydrogen is the most preferred molecular weight regulator or chain transfer agent. A particular advantage of using the present invention is its ability to produce narrow molecular weight distributions of ethylene / a-olefin interpolymers (depending on reaction conditions). Such narrow molecular weight distribution polymer products are highly desirable due to reduced levels of extractable material and metal values as well as improved tensile strength properties.

Without limiting in any way the scope of the present invention, one means for carrying out the polymerization process of the present invention is as follows. In a stirred-tank reactor, the monomers to be polymerized are introduced continuously with any solvent or diluent. The reactor contains substantially a liquid phase consisting of any solvent or diluent and dissolved polymer together with the monomers. The catalyst, together with the cocatalyst and optionally the chain transfer agent, is introduced continuously or intermittently into the liquid phase of the reactor or any recycled portion thereof. The reactor temperature can be adjusted by adjusting the solvent / monomer ratio, catalyst addition rate, as well as by cooling or heating the coil, jacket or both. The rate of polymerization is controlled by the rate of catalyst addition. The pressure is controlled by the monomer flow rate and the partial pressure of the volatile components. The ethylene content of the polymer product is determined by the ratio of ethylene to comonomers in the reactor, which is controlled by controlling the feed flow rate of each of these components to the reactor. The molecular weight of the polymer product is optionally adjusted by adjusting other polymerization parameters such as temperature, monomer concentration, or by the flow rates of the chain transfer agents mentioned above. Upon exiting the reactor, the effluent is contacted with a catalyst quenching agent such as water, steam or alcohol. The polymer solution is optionally heated and the polymer product is recovered by evaporation of the gaseous monomers as well as residual solvents or diluents under reduced pressure and, if necessary, further devolatilization is carried out in equipment such as a devolatilization extruder. In a continuous process, the average residence time of the catalyst and polymer in the reactor is generally 5 minutes to 8 hours, preferably 10 minutes to 6 hours.

Alternatively, the polymerization may be carried out in a continuous loop reactor in the presence or absence of a gradient of monomers, comonomers, catalysts or cocatalysts built between different regions of the reactor, optionally with separate addition of catalyst and / or chain transfer agent, And under adiabatic or non-insulating solution polymerization conditions, or a combination of the above reactor conditions. Examples of suitable loop reactors and various working conditions suitable for use with them can be found in USP 5,977,251, 6,319,989 and 6,683,149.

Multiple reactor polymerization processes are suitably used in the present invention. Examples include, in particular, systems such as those disclosed in USP 3,914,342. Multiple reactors can be operated continuously or simultaneously using one or more catalyst compositions according to the invention used in one or more reactors. One reactor or both reactors may contain two or more catalysts having different comonomer introduction and / or different molecular weight performance. In one embodiment, a relatively high molecular weight product (M _w is greater than 100,000 to 1,000,000, more preferably 200,000 to 500,000) is formed, and a relatively low molecular weight (M _w is 2,000 to 300,000) product is formed in the second reactor. do. Both of these reactor products may have similar or different densities. The final product is a mixture of two reactor effluents, which are combined prior to devolatilization which gives a uniform mixing of the two polymer products. In another embodiment, the molecular weights of the products from the two reactors are about the same, but the density is such that one of the reactors forms a polymer having a density in the range of 0.865 to 0.895, while the other reactor has a different density in the range of 0.885 to 0.950. Vary to form. This dual reactor / dual catalyst process allows the production of products with tailored properties. In one embodiment, the reactors are connected in series, that is, the effluent from the first reactor is directed to the second reactor and fresh monomer, solvent and hydrogen are optionally added to the second reactor. Reactor conditions are adjusted such that the weight ratio of the polymer produced in the first reactor to the polymer produced in the second reactor ideally ranges from 20:80 to 80:20. One skilled in the art recognizes that polymers having extended molecular weight distribution or polydispersity index (PDI) can be produced from the dual reactor process. Preferred polymers prepared in this way have a PDI of 2.8 to 6.0, more preferably 3.0 to 5.0. In a preferred embodiment, the high molecular weight component also contains a greater amount of comonomer (lower density) compared to the low molecular weight component.

In another embodiment, one of the reactors in the polymerization process (including the first reactor of two continuously operated reactors) is a heterogeneous Ziegler-Natta catalyst or a chromium containing catalyst such as many catalysts known in the art. Contains one. Examples of Ziegler-Natta catalysts include, but are not limited to, titanium based catalysts supported on MgCl ₂ , which further include aluminum compounds containing at least one aluminum-alkyl bond. Suitable Ziegler-Natta catalysts and their preparation include, but are not limited to, those disclosed in USP 4,612,300, 4,330,646, and 5,869,575. Suitable chromium based catalysts are those disclosed in USP 4,981,927, 4,835,219, 4,564,660, 4,173,548, 3,953,413 and the like.

Multiple catalyst processes in a single reactor are also useful in the present invention. In one embodiment, two or more catalysts are introduced into a single reactor at the reaction conditions disclosed herein, wherein each catalyst produces a uniquely different polyolefin copolymer. In one embodiment, a relatively high molecular weight product (M _w is greater than 100,000 to 1,000,000, more preferably 200,000 to 500,000) is formed from one catalyst and the relatively low molecular weight (M _w is 2,000 to 300,000) product is different It is formed from a catalyst. Both of these catalyst compositions can have similar or different comonomer incorporation capacity. The resulting polymer has properties that depend on the ratio of the two catalysts used in a single reactor. If a transfer agent is used, multi-block copolymers comprising polymer segments having different compositions and physical properties can be prepared in one or more reactors. Suitable combinations of polymer molecular weight, comonomer incorporation capacity, methods and catalyst ratios for such products are disclosed in USP 6,924,342, WO 2005/090425, WO 2005/090426 and WO 2005/090427. Due to the unique compatibility of the catalyst composition of the present invention with other olefin polymerization catalysts (including Ziegler / Natta catalysts), the second catalyst composition is a metal containing a metal complex, metallocene or other π-linked ligand group as disclosed herein. Complexes (including metal complexes of constrained geometry), or metal complexes containing polyvalent heteroatomic ligand groups different from the complexes of the present invention, in particular complexes based on polyvalent pyridylamine or imidazolylamine and tetradentate oxygen-regate ( oxygen-ligated) biphenylphenol based Group 4 metal complexes.
